Similar Solids

So what happens to a solid’s perimeter, area, and volume if you double the edge length? That’s what we looked at today. We started class going over HW #4 review on the board. We then did a quick investigation followed by some examples of BM 26. Here are the notes and the HW is #5 Similar Solids WS.

BM 25-27 Review

First off, we check #3 from over the weekend and went over it. The we took our first HW Quiz (#1). After that, we just continued to review for BM 25-27 on similar triangles.

Homework: BM 25-28 Review (BM 28 is optional right now). Also, bring a calculator if you have one.

8.4-8.5 Similar Triangles

Now the benchmark problems!

Today we looked at similar triangles. The main way to prove triangles are similar, some additional ways to prove they are similar, and some examples of the upcoming benchmarks (BM 25, 27, and 28). Notice there are a lot of “proving” triangles are similar? Don’t let that get you down, it’s our only “proof” benchmark.

The assignment for today is #3 483 #9-27 (odd), 39-47 (odd), 50-53, 55, 62-65. We will continue with these sections next week.

Coming Up: HW Quiz on Monday, 1/14

Posting for Points Question:

What are the various ways to prove triangles are similar?
